Persona is easy to use. With just two clicks a Persona user can sign into a new site like Voost, bypassing the friction associated with account creation.

Persona is easy to implement. Developers can add Persona to a site in a single afternoon.

There's no lock-in. Developers get a verified email address for all of their users, and users can use any email address with Persona.

Plus, Persona is only going to get better: it's built on an open, decentralized protocol that's designed to allow direct integration into browsers and native support by email providers. Sites that implement Persona today will automatically experience those improvements, without having to change any code.
